In recent century every home has a television. You can sit at home and see what is happening in the world every day. The world is shrunken by the performance of television which will show you the disaster in Africa happened just an hour ago.
But, we must be careful not to be a slave of television. It is because many people are sitting at home watching television as their daily life. They fall their heart too deeply into television.
It is, of course, not good for old people to sit on the sofa all day long to watch television which will make them to slow down their blood circulation and cause them various illness from over-watching television.
Television programmes are mostly on amusement which contents are already fixed by directors whose work is to make profit. Therefore, you can learn nothing from television, unless you select some programme of education or documentary.
Documentary is good for our knowledge. Many photographers, risking their lives, went to high mountains and dense forests to take photos about wild animals which we shall have no chance to see by our own.
Therefore we must have wisdom to select what is good to us or what is not. If we see television aimlessly, we shall waste a lot of time which can be used to our life more meaningfully.
